Routine AC unit preventive maintenance

Question

My MH has 3 ac units on it. I keep the filters clean on a regular basis. Really don't have any problems with them and wanting to keep it that way. Just wondering if there is any other routine maint that these units need. I clean my home AC unit with coil cleaner about twice a year. Just curious, do most just run them til fail or what..??

I oil the motors twice a year and clean the coils once a year.

Cleaning the coils will get you up on the roof removing the covers where you'll find any birds nests that have been built. Get the foaming cleaner, it pushes the dirt out.

Clean coils twice a year, filters monthly...but we fulltime. Never have oiled motors. Our 2 15,000 BTU Coleman heat pumps, the front unit has been changed out due to compressor failures three times, the rear unit has only had a hard start capacitor installed. Bought the RV new in December 2005, units basically run whenever we are in it.

Check the condenser coil for damage from hail and stuff, if fins are folded/ damaged,  order fin comb off Amazon   https://www.amazon.com/Diversitech-T-400-Tool-Super-Comb/dp/B004493K96/ref=sr_1_9?ie=UTF8&amp;qid=1498616289&amp;sr=8-9&amp;keywords=fin+comb
